The first thing you'll notice, when you run in the dark, is the lack of light.

This may seem like a small thing, a minor detail. But it is not. It is critical to understanding darkness, as a runner, and learning to outwit it. And outwit it you must. Because when it is dark, it is difficult for motorists, cyclists, and other pedestrians to see you. Due to the lack of light. This increases the risk of accidents, such as collisions.

Also when it is dark, it is hard to spot and avoid hazards in your path. Due, again, to the lack of light. This increases the risk of accidents, such as falls.

If you think this sounds like obvious advice, you are wrong, wrong, wrong. Because Dumb Runner routinely sees runners—just barely, and at the last minute—out well after sunset dressed in dark clothing and nothing in the way of reflective gear or lights.

She passed us, crossed the street, and ran on.

Also, she was wearing ear buds.

Readers, this article is dedicated to this young woman and to the multitude of runners out there who take a similar approach to night-running safety, i.e., no approach.
